Description

technical field [0001] The invention relates to the related technical field of comprehensive utilization of solar energy, in particular to a simple solar energy coupling wind energy air heating device. Background technique [0002] Solar energy, a renewable energy source, refers to the thermal radiation energy of the sun (see the three ways of thermal energy transmission: radiation), the main performance is the often-called sunlight, which is generally used to generate electricity or provide energy for water heaters in modern times. Since the birth of life on earth, it has mainly survived on the thermal radiation energy provided by the sun. Since ancient times, humans have also known to use sunlight to dry objects and use it as a method of making food, such as making salt and drying salted fish. Under such circumstances, solar energy has become an important part of human energy use and has been continuously developed. There are two ways to use solar energy: photothermal con...

Problems solved by technology

There are two ways to use solar energy: photothermal conversion and photoelectric conversion. Solar power generation is a new type of renewable energy. In a broad sense, solar energy also includes wind energy, chemical energy, water energy, etc. on the earth. Solar energy is a typical renewable energy source. , are widely distributed and easy to use. In the field of renewable energy, the proportion of solar energy resources has steadily increased. At present, the utilization of solar energy resources is mainly in two forms: solar energy-electric energy and solar energy-thermal energy. In the process of utilization, the problem of low energy conversion efficiency is generally faced, and there are certain differences in energy grades, resulting in low system operation efficiency and high investment costs

[0003] Common solar collectors can only supply domestic hot water. Due to the large specific heat capacity of water, the temperature rise of the air is higher when receiving the same solar radiation. In some cases, hot water cannot be used due to low temperature, resulting in differences in energy grades. As a result, the utilization efficiency of the system is low. At present, the solar collectors used in commercial applications are generally large in size, and the flexibility of site selection and installation is not high, and they cannot be installed in the form of hanging on the wall. The proposed solar energy coupling electric energy air heating device has a simple structure, which not only reduces the floor area but also reduces the investment cost. At the same time, due to the low specific heat capacity of the air, combined with the trough-type concentrating device, the comprehensive utilization efficiency of the system is effectively improved. , increasing the outlet temperature of the air
